Figure 5: The FO-PMD statistical distribution for (a) link 61-62 and (b) link 81-82 and the accompanying SO-PMD statistical distribution for (a′) link 61-62 and (b′) link 81-82. The solid line mapped to the FO-PMD histogram is the theoretical Maxwellian distribution and that mapped to the SO-PMD histogram is the theoretical distribution proposed by Foschini et al. [26].
